Answer:

The answer is D(20)

Step-by-step explanation:

I don't know the exact algebraic explanation, however, this is how I did it.

$2^5+2^5=$ $2*2^5$

If you divide the second equation into seperate twos, you will get 2*2*2*2*2*2 = $2^6$

Therefore, $2^x=2^6$ meaning that x is equal to 6. Now The next bit is trial and error, 20-6=14. $3^{y} = 3^{14}$

Last thing to do is to add x+y=6+14. That is why the answer is 20.

If you wait a bit longer, someone will probably have a more algebraic explanation, however, you stated you only needed the answer so I hope this helped.

What is the constant of variation if y varies inversely as x and y = 3 when x = 6? PLZ HELP ME I DONT UNDERSTAND

mojhsa [17]

Answer:

k = 18

Step-by-step explanation:

Given that y varies inversely as x then the equation relating them is

y = $\frac{k}{x}$ ← k is the constant of variation

To find k use the condition y = 3 when x = 6, that is

3 = $\frac{k}{6}$ ( multiply both sides by 6 )

18 = k

The constant of variation is k = 18

Find two positive numbers so that twice their sum equals their product and one number is 10 times the other number. Enter the sm

Softa [21]

Answer:

Step-by-step explanation:

We'll call the 2 numbers x and y. Starting with the last part of that first sentence "one number is 10 times the other number" can be written, in algebraic form:

y = 10x

Now on to the first statement about the numbers: "twice their sum" is 2(x + y) and "equals their product" is = xy. Putting that all together:

2(x + y) = xy and we know that y = 10x so

2(x + 10x) = x(10x) and

$2(11x)=10x^2$ and
